Fresh setup on a newly created Grail 2.3.5 plugin project. Update to
Grails 2.3.5. Removed dependency for Font-Awesome (Bootstrap uses
Glyphicon's Icon-Font now). Correction of "alert-error" into
"alert-danger" - changed in Bootstrap 3 (Tip by Leo Bartoloni). Fix for
display:none in scaffolding (Merged by "stlhrt")
